Precise notes: postponing all remaining work due to impending feature freeze and barry shifting gears to stable+1 maintenance. As time allows, I'll remark specific items as INPROGRESS and continue working on landing those changes upstream and in Debian. Porting u-m will continue in earnest for the Q-cycle.

update-manager is the selected application. Here is its (Python) dependency stack, with Python 3 status and some additional notes after chatting w/mvo.

- python-boto (maybe just for ec2 testing?)
  status: port needed
  mvo: can kill it off

- PyQt4
  status: python3-pyqt4

- gconf
  status: unknown
  mvo: kill it off

- python-gnupginterface
  status: port needed
  mvo: or just call subprocess directly
  mitya57: there's a more active project, and it supports python3: http://code.google.com/p/python-gnupg/

- PyKDE4
  status: Python3 port exists upstream - needs packaging, not sure why port to Qt?
  mvo: port to qt

- aptdaemon
  status: unknown
  mvo: waiting for dbus, upstream wants to port it
       * a really good start

- python-apport
  status: pitti says problem_report.py needs bytes/str fixes

- python-debian
  status: pending upstream review; http://bugs.debian.org/625509

- python-mock
  status: done by upstream/Debian in 0.7.2-1

- ??? check_new_release_gtk
  tests/test_end_of_life.py:31
  mvo: probably already dead

- mvo: maybe get rid of lsb-release in favor of `import platform`

- mvo: update-manager-text should die
